All solar batteries degenerate in performance and lifespan from a process called sulfation. Sulfation is a build up of an insulating layer of spongy sulfate crystals which occurs whenever a battery discharges. The live of the battery or active material become lodged in an unusable crystalline form. The process reverses whenever the batteries are charged. However since the amount of time where a battery is discharging is higher than when it is charged, over time the sulfate crystals harden and cannot return as active material even with charging.
A customer from Canada recently sent us images of his installation of four 24V Infinitum Desulfators on his 24V solar battery bank made up of eight 12V batteries. We see here four parallel rows of two 12V batteries in series. One 24V desulfator is installed on each two 12V batteries in series.
Below is the image of the actual installation, an illustration of that installation as well as an example of a 48V battery bank setup with 24V Infinitum Desulfators.

Tamz left this testimonial on Facebook of how he managed to recover his solar batteries that were no longer able to accept a charge. In the image you would note how he has hooked up the 24V Infinitum Desulfator in parallel with two 12V batteries that are hooked up to make up 24V.
The testimonial is a mix of Filipino and English. Below is the translation:
Mike from Philippines successfully revived his solar batteries which at 4-years-old began to show a significant drop in performance. Mike placed the desulfator into action having promptly received his order. Here is the English translation from the Facebook testimonial he posted:

Note from Infinitum:
We received an update on our Google Plus page from Keith van Dijk today on how well our desulfators are performing as an integral part of his solar setup.
Keith made his first purchase of four 24V Infinitum Desulfators in August 2013. He purchased them for A$280 instead of the A$600 he mentioned here. We can't fault him here as he purchased them quite long ago. The amount he paid for the solar battery banks came up to A$12,000. With a modest assumption that the lifespan is doubled from the many testimonials we've received, the ROI (return on investment) for the $280 spent is a whopping 4,186%!

We received an order for 100 12V Infinitum Desulfators for yet another solar street light installation in Papua, Indonesia. In the first Papua solar street light project spanning a period of one year from June 2012, 800 solar street lights were installed in several towns in this easternmost part of Indonesia. Each street light was powered by a 12V 100AH battery with a our desulfators installed.
Following on the success of the initial projects, the Indonesian government decided to extend the use of this form of street lighting made even more eco-friendly by the optimized battery life span, to Manokwari, the capitol city of the province of West Papua. With an initial installation of 100 street lights, this city is headed towards a greener and cleaner environment, essential to its tourist-driven economy.
"I revived my 5 year old portable Century Jumper 850 jump starter battery with the Infinitum battery desulfator. I am so convinced that I am also using it on my deep cycle solar batteries"
Floral Park, New York, United States
Note from Infinitum:
Wai Tam managed to revive his 5 year old sealed lead acid battery located inside the Century 850 Jump Starter with the Infinitum Desulfator. After charging the battery for 5 to 6 hours over 2 to 3 times he left the battery for a week to discover then that the battery had successfully been revived being able to hold its charge.
As a battery sulfates its capacity to hold a charge drops. You will note this from the quick drop in voltage despite of a full charge.
The good news is, with the Infinitum Desulfator, Wai Tam successfully reversed the destructive process of sulfation and optimized the health of the battery. Watch the video below:
"A scrapped battery I purchased for A$5.00 in April 2012 is still functioning today!
My son and I have not bought a new battery for at least three years,
and none of our batteries have died since fitting the units."
Toyota Landcruiser and Scrapped Battery Optimised
As far as performance of the Infinitum desulfators, I have one on each of the two batteries in my Toyota Landcruiser. One of the batteries was about 5 years old and probably near the end of its life, when I fitted the first unit (desulphator) in March 2012. This battery is still starting the cruiser.
The other battery is one I picked up outside a tyre service for scrap price of $5.00. I immediately fitted a desulphator and it is still running my 12 volt fridge/freezer as well as auxiliary starting. That was in April 2012.
